My invention relates to a method of and apparatus for ianging containers, such as barrels, drums or the like, whereby a seat is provided for a cover plate or other closure means, and it is an object of the invention toV provide a mechanism of this kind which is simple in construction, inexpensive to marufacture, and easy to operate. Other objects and advantages of the invention will be apparent from rthe following description and the features of novelty will be pointed out in the appended claims.

An embodiment of my invention is illustrated by way of example in the accompanying drawings in which Fig. 1 is a top plan view Aof the' platform carrying the Hanging rolls, illustrating the position assumed by the parts at the end of the Hanging process proper; Fig. 2 is a section along line 2-2 of Fig. 1; Fig. 3 is a partial section along line 3-3 of Fig. 1; Fig. 4 is a partial top plan view of the latform, the clamping roll being removed; ig. 5 illustrates in perspective view the complete machine; and Fig. 6 is a. perspective view of the platform with its co-ordinated parts. f Y

The pedestal 10 (Fig. 5) carries in its offset upper end a vertical shaft 11 provided with a pulley 12 and a disc 13 arranged to be driven from a suitable motor, not shown, by means of the belt 14. The disc 13 is provided with a shoulder 14 over which the upper edge of a container, such asa barrel or drum shell may be slipped to abut against the disc 13 to which the barrel or drum is then attached in any suitable manner, for instance, by clamping screws, not shown. The barrel or drum shell is thus held in position to be positively rotated about its longitudinal axis. The pedal 15 shown at the foot of the pedestalserves to operate a switch for the control of the motor which drives the pulley 12. While the barrel is being rotated, its lower edge is operated upon by the flanging tools which will be. described hereinafter.

The pedestal 10 is provided with a vertical guide 16 to accommodate slidingly a carriage 17 in which a horizontal shaft 18 is journalled. This shaft carries a hand wheel 19 and a pinion 20 meshing with a rack 21 FOR FLANGING CONTAINERS 341,581, and in Germany November 27, 1988.

thereon is more clearly illustrated in Figs. 1,

2 and 6. It comprises a plate formed in its central part with a sleeve-shaped portion 25 which is slipped over the upper end of post 23 which is preferably of rectangular crosssection and abuts against a shoulder 26 on said post, and is kept in place by means of a washer 27 and a bolt 28. The platform 24 is provided with five radially disposed slots 29 serving to accommodate adjustable guiding devices designed to guide the lower edge 'of the revolving barrel shell which is clamped at its upper ledge to the disc 13. Each of these guiding devices comprises a block 30 (Fig. 2) carrying a vertical pivot 31, preferably integral therewith, a horizontal pivot 32 mounted inthe block and a lower section 33 of rectangular cross-section slidingly arranged within the slot 29. A clamping nut 34 screwed on a threaded projection 35 of portion 33 serves to keep the block 3() firmly in position. On pivot 31a single guiding roll 36 is mounted while the pivot 32 carries two guiding rolls 37 and 38 capable of independent rotation. The rolls 36 and 37 serve to guide a revoluble ring 39 dimensioned to receive the barrel shell 40 (Fig. 2). The rolls 38 function as abutments for the lower rim of the barrel shell when the latter is introduced into the machine, while ring 39 serves to cooperate with a roll 41 to support the shell positively near the point at which it is worked upon by the Hanging tools during the Hanging operation.

The roll 41 is arranged in the lane and inside of ring 39 and iscarried y a vertical pivot 42 depending from a bar 43. In order to permit the adjustment of the roll 41 to rings 39 of different diameters corresponding to barrels of different size, the bar 43 is adjustably mounted on a carrier 44 by means of a pin and slot connection 45. Furthermore the carrier 44 is shiftable within predetermined limits so that a barrel shell clamped between roll 41 and ring 39 may easily be released for the purpose of removing the f`1n ished shell and inserting a new one. To thisy end the carrier 44, more clearl shown in Fig. 3, is pivotally mounted on a olt 46 inserted in the platform 24 eccentrically of the barrel, and is provided with an outwardly extending arm 47 carrying at its end a sleeve 48 in which a spring-,pressed block 49 having a handle 50 1s mounted. The block 49 is arranged to engage Aalternatively one of two recesses 51 in thevrirn of platform 24 so that, when the block 49 has been withdrawn from its recess by means of the handle 50, the carrier 44 may be shifted and the pressure roll 41 may be withdrawn from its operative position to release the barrel shell 40.

The flanging tool proper is formed by a pair of rolls 52 and 53 having their upper faces arranged in close proximity to the lower face of ring 39 and spaced from the lower face of roll 41 by a distance equal to the thickness of the sheet metal to be operated upon. Each roll is provided with an axle 54 or 55 respectively, which is rotatably journalled within a rectangular block 56, or 57 respectively (Figs. 2 and 4). Nuts 58 serve to keep the axles in place. Both blocksI are guided within a slot defined by arms 59 of the platform 24` and are provided with lateral flanges 60 bearing upon the finished faces of said arms. The radial slot defined by arms 59 extends in inward direction up to the sleevey shaped portion 25 and is closed at its outer end by a cross-head 61 bolted to the end of the arms 59. This cross-head is provided with a central boring rotatably accommodating a sleeve 62 (Fig. 1) having attached and keyed to its outwardly projecting end a hand wheel 63. The sleeve is threaded and in engagement with a threaded spindle 64 which is rigidly attached to block 56, so that the latter by rotation of the hand wheel 63. may be positively displaced in the slot defined by the arms 59.

Block 56 is. furthermore, provided with two horizontal borings through which headed bolts 65 extend in inward direction to block 57 into which their ends are screwed (see Figs. 1 and 2). Each of these bolts, is surrounded by a compressed spring 66 abutting. at the one side, against the heads of bolts 65 and, on the other side, against suitable shoulders provided within the borings of block 56. These springs tend to urge the blocks 56 and 57 toward each other so that the marginal portion of the barrel shell inserted between the rolls 52 and 53 is firmly clamped therebetween. The blocks are kept an adjustable distance from each other by adjustable abutment screws 67. Furthermore, the inner block 57 is provided with a pin 69 (Fig. 1) cooperating with a stop member 70 which serves to limit the movement of the block. The member 70 is seated upon the one arm 59 and held in adjustable position by means of a bolt 71, and is formed with a recess within which the pin 69 is adapted to move.

The machine is operated in the following manner: Y

Preparatory to the flanging process proper, a ring 39 of suitable diameter corresponding to the diameter of the barrel shell is selected and inserted in the machine upon proper adjustment of the guiding blocks 30. The platform 24 is lowered by means of hand wheel 19, and the barrel shell is slipped over shoulder 14 to be attached to thel rotatable disc 13. )Vhen this has been accomplished, the platform 24 is raised again until the lower end of the barrel shell enters ring 39, its entrance being facilitated by the inclined face of the ring until it abuts against the rolls 38. During this phase of the operation, the carrier 44 assumes the position in which the supporting roll 41 is withdrawn from the ring so that the lower end of the shell may readily be inserted, and the blocks 56 and 57 are so adjusted that the gap between the rolls 52 and 53 is in registry with the shell. When this has been done, the handle 50 is pulled out and the arm 47 is swung into the position shown in Fig. 1 in which the supporting roll 41 firmly bears upon the inside of the shell. To insure such a firm contact the bar 43 mustbe adjusted accordingl and, subsequently, be tightly clamped in place on its carrier 44 by-means of a wedge 68 (Figs. 1 and 3).

The pedal 15 is then operated to start the revolution of the barrel shell and, when the same has acquired its full speed, the hand wheel 63 is turned to press block 56 gradually in an inward direction until it reaches the position shown in Fig. 2. In the course of the advance of block 56, the flange 72 is formed on the lower edge of the shell, while the marginal section 73 of the shell is tightly clamped between the rolls 52 and 53 owing to the action ofthe springs 65. The flanging operation is completed as soon as the pin 69 reaches its inlermost position, illustrated in Figs. 1 an 4.

Upon completion of the flanging operation,-

the edal 15 is released to stop the machine, han le 50 is pulled out and arm 47 is swung into its other position, in which the pressure roll 41 is withdrawn from ring 39 and from the freshly formed flange or shoulder 72 to permit the platform 24 to be lowered by means of the hand wheel 19. The barrel shell may then be released from the disc 13 and the next cycle initiated by turning the .hand wheel 63 back until the pair of rolls 52 ,and 53 are so located as to permit the insertion of a new barrel shell.

It will be 'understood that while I have v lmember or roller 41 to engage the exterior face 'of-the barrel while the position of the rollers 52 and 53 is reversed and the block 56 caused to be moved outwardly, sothat pressure is exerted against the interior .face of the barrel. It will also be recognized by those skilled in the art that the barrel'may be supported at the bottom and the langing performed at the top, and that instead of being operated by a hand wheel 63, the

spindle or screw 64 'could be rotated by other means, such asa motor. It will also be clear that instead of moving the rollers 52 and 53 relatively to the barrel, the latter could be moved relatively to-the rollers. Moreover, the barrel could be supported with its axis in a horizontal position, the flanging apparatus being suitable re-arranged. Other variationsmay be resorted to within the scope of the appended claims without departing from the spirit of the invention.
